INterSECT - Resistance against thrips

Pyrethrum is over 100 years a source of a broad-spectrum botanical insecticide. By studying mechanisms of resistance and insulation of the relevant genes in pyrethrum, we expect much insight into how these plants are chemically defends against insects and how we can apply this in other crops.

The aim is to characterize biochemical and genetic basis of existing resistance against thrips and TSWV transmission in cultivated and wild chrysanthemum (pyrethrum). For this purpose, we analyze the biosynthetic pathway leading to both high jasmonate as high pyrethrin production in plant tissue surrounding the ovary.

Jasmonate is a universal wound hormone that induces resistance to insects by regulating a wide range of resistance genes. A jasmonalcohol and a terpene chrysanthemylzuur, the two substrates via a esterificatiestap lead to the synthesis of pyrethrins, the most effective botanical insecticide that we know.

This project develops knowledge on the most generic and most potent means of regulating insect plant there is. The project focuses on thrips and virus transmission resistance, but the principles offer generic, sustainable solutions for many other insect-plant problems.

The result is knowledge about the most generic, and the most potent insect-regulating means of plant there is. The principles provide generic, sustainable solutions for many insect-plant problems.
